Badge of the Night(夜の勲章)

A noir action whodunit with Kobayashi his usual jaunty self as the smart aleck private eye whose missing person search soon becomes a murder case. Nightclub-managing, drug-dealing gangster Uchida is the prime suspect in the case until he commits suicide. Kobayashi then discovers evidence that points to the doctor sibling of an innocent girl. The climax in a rural snowy locale is suspenseful and well-staged.
